Mobile phone masts

Phone mastPhone masts expose most people on a daily basis to some degree, particularly those who live in cities where you can find small, wall mounted "masts".

The large masts broadcast their signal out very much like light from a lighthouse, and therefore the exposure directly below the mast is fairly low. Typically the main beam meets the ground between sixty and 150 metres away depending on the geography and equipment settings, although obviously this is closer in upstairs rooms of a house. Wall mounted ones in town streets however can expose nearby residences highly, so it is not that rare to find people exposed to sources they did not even know existed in built up areas. In rural areas, higher power transmitters are used to cover larger areas, so the spread of high fields can be larger.

The best way to check for radio frequency exposure levels (caused by most wireless devices) is to use a suitable instrument such as an Acoustimeter. You can purchase this instrument or another, cheaper (but still highly accurate) alternative such as the Acousticom 2.

We sell instruments to measure electromagnetic field exposure from sources such as electricity substations and transformers, powerlines and mobile phone masts, and offer a number of protective shielding solutions for those who find themselves highly exposed. We also provide a list of some EMF Surveyors on our surveys website.

Alert message Customer Service

We have designed all of our own instruments which are manufactured in the UK and have a 2-year return-to-base warranty. We are able to zero-rate UK VAT on certain items, if you have selected that you are Electrically Hypersensitive in your profile.

We can ship most of our products world-wide.
